Detailed Description

template<class T>
class EBGeometry::UnionIF< T >

Implicit function whose interior is the union of all input function interiors.

A point is inside UnionIF if and only if it is inside at least one stored function. The value at any point is the minimum over all stored functions; a negative value indicates membership in the union.

Template Parameters

T	Floating-point precision.

Constructor & Destructor Documentation

UnionIF()

template<class T >

EBGeometry::UnionIF< T >::UnionIF

(

const std::vector< std::shared_ptr< ImplicitFunction< T > > > &

a_implicitFunctions

)

Constructs the union of the given implicit functions.

Parameters

[in]

a_implicitFunctions

List of implicit functions (must be non-empty; no null entries).

Member Function Documentation

value()

template<class T >

T EBGeometry::UnionIF< T >::value ( const Vec3T< T > &  a_point ) const

overridevirtualnoexcept

Evaluates the signed distance at a_point.

Returns the minimum over all stored functions. Negative when inside the union.

Parameters

[in]

a_point

3D query point.

Returns

Minimum signed distance value among all stored functions.

Implements EBGeometry::ImplicitFunction< T >.
